What If Every Product in Keepa Already Told You Whether You Could Sell It?

Let me paint a picture you'll recognize.
You sit down to source. You open Keepa Product Finder, set your filters, and start scrolling. A product catches your eye. Good rank. Decent price. Low seller count. This could be the one.
So you open the listing. Check the graph. Pull up Seller Central in another tab. Navigate to the eligibility page. Paste the ASIN. Wait for it to load. And then—
"You need approval to sell this product."
Fifteen minutes. Gone. On a product you never had a chance of listing.
Now multiply that by the 30, 50, or 100 products you look at in a sourcing session. How many hours have you lost this month to products you can't even sell?
That's why I built SourceLens.
It does something remarkably simple: it checks your Seller Central eligibility for every single product visible in Keepa—automatically, in the background—and shows you a colored dot right on the row. Green means you can sell it. Yellow means you need approval. Red means skip it.
No tab switching. No copy-pasting ASINs. No waiting. You just... source.
But that's only where it starts. Let me show you everything it does.
Three Problems That Silently Drain Your Profits
Most OA sellers don't realize how much time and money these issues cost them every single week.
You research products you can't list
At 10-15 minutes per product, checking eligibility manually on just 20 gated products wastes 3-5 hours of your week. That's an entire sourcing session spent accomplishing nothing.
Competition blindsides you after you buy
A product looks great today. But 14 new sellers jumped on it this month. By the time your shipment arrives at FBA, the Buy Box price has cratered. You had no way of seeing it coming.
Tab switching eats your focus
Keepa. Seller Central. Google. Retailer sites. Spreadsheets. Every context switch costs you 20+ seconds and breaks your concentration. Over a session, it adds up to hours.
Instant Eligibility on Every Keepa Row
The moment you open Keepa Product Finder, Deals, or Product Viewer, SourceLens starts working. Every row gets a colored dot. Every product is categorized. You never have to check Seller Central manually again.
- Green, yellow, and red dots on every row—automatically
- Three-tier caching means repeat products load instantly
- One-click "Request Approval" on yellow rows attempts auto-ungating
- Filter toolbar hides restricted/gated/reviewed rows with one click
- Mark products as "Reviewed" with a purple tint that auto-expires
- Brand, category, and condition data extracted from every check
See Exactly When the Buy Box Has Been Above Your Break-Even
Enter your break-even price on the Amazon product page. Click one button. Keepa opens with a dashed orange line drawn at your exact target — so you can see at a glance how often, and for how long, this product has been profitable.
Open in KeepaEach ASIN remembers its own break-even price. The line reappears every time you open that product in Keepa.
✕Essential Tools Built Into Every Keepa Row
Each product row gets a full toolkit. No tab switching. No copy-pasting. Everything is one click away, right where you're already looking.
Deal Scorecard (1-10)
Auto-scores every product on competition, seller trends, demand stability, and price consistency. Configurable weights so you can tune it to your categories.
Competition Trend Arrows
See instantly if seller count is rising (danger), falling (opportunity), or stable. Compares current FBA count against 30-day and 90-day averages.
Google Search Panel
Click the search icon on any row to open Chrome's side panel with Google results for that product. Research without leaving Keepa.
Retailer Source Finder
One click searches for any product across 23 built-in retailers (Walmart, Target, Chewy, etc.) or your own custom retailer list.
Product Notes
Leave notes on any product from the row. "Passed — too volatile" or "Bought 6 from Target." Notes persist and are visible the next time you see that ASIN.
Reviewed Marker
Mark products you've already evaluated. The row turns purple. The mark auto-expires after 14, 30, 60, or 90 days so products cycle back naturally.
Copy Menu
One click to copy the ASIN, product title, Amazon URL, or all three. No more highlight-copy-switch-paste gymnastics.
